Summary: Predicted to enable oxidoreductase activity, acting on paired donors, with oxidation of a pair of donors resulting in the reduction of molecular oxygen to two molecules of water. Acts upstream of or within gene expression and unsaturated fatty acid biosynthetic process. Predicted to be located in endoplasmic reticulum membrane. Is expressed in nervous system; retina; and thoracic segment skeleton. Orthologous to human FADS3 (fatty acid desaturase 3). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
